Frequently Asked Questions (FAQ)

Q: Is the XC2S200-6FGG1249C RoHS compliant?

Yes. The “G” in the “FGG” package designation indicates this is the Pb-free (lead-free) packaging variant, compliant with RoHS directives.

Q: What is the difference between XC2S200-6FGG1249C and XC2S200-6FGG456C?

The primary difference is the pin count and package size. The FGG1249 package has 1,249 pins versus 456 pins, providing a significantly larger footprint with higher I/O density capability. Both devices contain identical XC2S200 silicon with the same -6 speed grade.

Q: Can I use Vivado to program the XC2S200-6FGG1249C?

No. The Spartan-II family is not supported in Vivado. You must use Xilinx ISE Design Suite version 14.7, which is the last release that supports legacy Spartan-II devices.

Q: What PROM should I use to configure the XC2S200-6FGG1249C?

Xilinx XCF (Platform Flash) PROMs or legacy XC17V series PROMs are compatible with Master Serial configuration mode. The XCF04S, XCF08P, or XCF16P are commonly used with XC2S200 designs.

 Q: Is the XC2S200-6FGG1249C still in production?

The Spartan-II family has been discontinued for new designs (per Xilinx PDN notice). However, inventory is still available from authorized distributors and the component is widely used in legacy system maintenance.

Q: What is the -6 speed grade compared to -5?

The -6 speed grade is the fastest available for commercial-temperature Spartan-II devices, offering lower propagation delays and higher maximum operating frequencies compared to -5. The -6 grade is exclusively available in the Commercial (0°C to +85°C) temperature range.

Summary: XC2S200-6FGG1249C at a Glance

The XC2S200-6FGG1249C remains a reliable, proven FPGA solution for engineers maintaining legacy designs or building high-I/O embedded systems.
